Effect of Dried Spleen as a Growth Promoter in the Ration of Crossbred Calves
An investigation was carried out to assess the effect of dried spleen as a growth promoter in the ration of crossbred calves. Twenty crossbred heifer calves of six to nine months of age were distributed randomly into four groups (group 1, 11, 111 and IV0 as uniformly as possible with regard to age...

Twenty crossbred heifer calves of six to nine months of age were distributed randomly into four groups (group 1, 11, 111 and IV0 as uniformly as possible with regard to age and body weight. The animals in groups 1, 11, 111 and IV were maintained on concentrate ration A containing 20 per cent crude protein, concentrate ration B containing 20 per cent crude protein and 0.1 per cent dried buffalo spleen, concentrate ration C containing 15 per cent crude protein and concentrate ration D containing 15 per cent crude protein and 0.1 per cent dried buffalo spleen respectively. The animals in groups 1, 11, 111 and IV showed average daily weight gain of 633, 667, 572 and 594 grams respectively. The animals in group 1 and 11 showed higher weight gain than those in group 111 and IV but on statistical analysis there was no significant difference among the four groups. The dried buffalo spleen biostimulator did not have any effect on change in body measurements viz. height at withers, body length and chest girth. The average daily drymatter intake of the animals in the four groups ranged from 5.04 to 5.12 kg and it was almost equal in all the groups. The average fortnightly feed efficiency ranged from 8.71 to 7.55. The animals in group 1 and 11 showing higher feed efficiency than those in group 111 and IV. However there was no significant difference between the biostimulator group (111 and IV) and its control (1 and 11). Though the animals in group 111 and IV had slightly higher protein efficiency than those in group 1 and 11, biostimulator feeding did not seem to have any significant effect on protein efficiency. The cost of production in terms of rupees per kilogram gain was almost the same for all the groups. The biostimulator did not have any effect on packed cell volume, haemoglobin concentration, erythrocyte count, leukocyte count and serum proteins. Incorporation of biostimulator did not alter the pH of rumen and concentration of fermentation products viz., acetate, propionate, butyrate and ammonia. The digestibility coefficients of drymatter, crude protein, ether extract, crude fibre, nitrogen free extract, neutral detergent fibre, acid detergent fibre, hemicellulose, cellulose and lignin did not differ significantly between biostimulator treated group and control. The animals in group 1 and 11 had higher digestibility coefficients for crude fibre, neutral detergent fibre, hemicellulose and cellulose than the animals in group 111 and IV. The digestibility coefficient for crude protein was higher in group 111 and IV. A critical assessment of the overall results obtained during the course of the present study indicates that addition of dried spleen biostimulator at a rate of 0.1 per cent in the ration did not have any effect on growth, feed efficiency, haematological value, rumen fermentation and nutrient digestibility in crossbred calves with an average daily gain of 600 grams per day. | |
